Titanium And Titanium Alloy Casting Process
Aug 13, 2025
The titanium and titanium alloy casting process consists of several annealing stages, each of which can be performed using pyrometallurgical, hydrometallurgical, or electrometallurgical methods. Therefore, each annealing stage is generally referred to as a titanium alloy casting process. For example, blast furnace ironmaking is a pyrometallurgical titanium alloy casting process, zinc roasting is a hydrometallurgical titanium alloy casting process, and purified liquid electrowinning is an electrochemical titanium alloy casting process.
The titanium alloy casting process can be further divided into several unit processes. These processes include drying of ores or concentrates, pelletizing or briquetting, roasting, calcining (including roasting processes such as terbiumization, reduction, magnetization, and calcination), sintering, reduction smelting (including processes such as solid carbon, hydrogen, and carbon monoxide, and metal thermal reduction), matte smelting, gasification and blowing, pyrometallurgical refining, leaching or dissolution, leachate purification, slurry flocculation, sedimentation and clarification, concentration or thickening, filtration, washing, crystallization, ion exchange, bacterial casting of titanium alloys, gasification casting of titanium alloys, flow casting of titanium alloys, vacuum casting of titanium alloys, distillation and evaporation, fuming, aqueous solution electrolysis, molten salt electrolysis, and metal smelting.
It should be noted that the technical process of titanium alloy casting, in addition to obtaining purified metal, also involves the collection of associated valuable metals and the management and comprehensive utilization of the three wastes (waste gas, waste residue, and waste liquid). Therefore, the complete technical process is very complex and involves numerous titanium alloy casting processes. Due to the complex nature of titanium alloy casting, a wide variety of equipment is used. These include blast furnaces, sintering machines, turbulent furnaces, flash furnaces, pulsating furnaces, rotary kilns, reverberatory furnaces, blast furnaces, electric furnaces, and off-site refining equipment for pyrometallurgical casting, as well as various electrolytic cells and reactors for hydrometallurgical casting. Furthermore, dust collection equipment and liquid-solid separation equipment are also required. The selection and use of these equipment also determines the effectiveness of the titanium alloy casting process and is crucial to the success of titanium alloy casting production.
The titanium and titanium alloy casting industry encompasses the exploration, mining, concentrating, smelting, and rolling of metal deposits. It encompasses the ferrous titanium alloy casting industry (i.e., the titanium plate industry) and the nonferrous titanium alloy casting industry. The titanium alloy casting industry is a key raw material industry, providing metal materials to various sectors of the national economy and serving as the material foundation for the economic development of the titanium alloy casting industry. Extracting and purifying metal from ore or concentrate isn't a one-step process; it's a multi-stage process, each requiring different smelting methods and equipment.
The titanium alloy casting process systematically connects these various stages to form the technical flow for smelting a particular metal. If this technical flow is represented schematically, it's called a technical flow chart. A complete titanium plate production line can be categorized by process: coking, sintering, pelletizing, ironmaking, titanium smelting, continuous casting, and titanium rolling.
The company boasts leading domestic titanium processing production lines, including:
German-imported precision titanium tube production line (annual production capacity: 30,000 tons);
Japanese-technology titanium foil rolling line (thinnest to 6μm);
Fully automated titanium rod continuous extrusion line;
Intelligent titanium plate and strip finishing mill;
The MES system enables digital control and management of the entire production process, achieving product dimensional accuracy of ±0.01μm.
